Description

Technical Field

[0001] This utility model relates to the field of central air conditioning, and in particular to a frame component of a central air conditioning system and a central air conditioning system. Background Technology

[0002] Central air conditioning consists of air handling equipment (such as combined air conditioning units and fan coil units), heat and humidity handling equipment (i.e., cold and heat sources or air conditioning main units), supply and return air ducts, and various terminal air outlet units (i.e., fan coil units or indoor units, etc.). A central air conditioning system consists of one or more cold and heat source systems and multiple air conditioning systems. It uses the principle of liquid vaporization refrigeration to provide the required cooling capacity to the air conditioning system to offset the heat load of the indoor environment. The heating system provides the required heat to the air conditioning system to offset the cooling and heating load of the indoor environment. The refrigeration system is a crucial part of the central air conditioning system. Its type, operation mode, and structural form directly affect the economy, efficiency, and rationality of the central air conditioning system during operation.

[0003] When inspecting central air conditioning systems, it is often necessary to disassemble and reassemble the frame grille of the air outlet. Existing publication number CN219797468U discloses a central air conditioning outlet, including an air outlet duct. An air outlet is slidably provided on one side of the air outlet duct, and a grille is fixedly provided on the air outlet. Two pairs of threaded rods are rotatably provided on the air outlet, each threaded rod having a threaded ring. Multiple handles are fixedly provided on each ring. A cylindrical sleeve is fixedly provided at one end of each threaded rod, and a pair of square grooves are opened on each cylindrical sleeve. A sliding groove is opened inside each cylindrical sleeve. A transmission rod is rotatably provided on each threaded rod, with a disc fixed at one end and a screw fixed at the other end. By adding rings and brackets, the air outlet is directly installed on the air outlet duct, improving the speed of air outlet installation and disassembly.

[0004] However, the aforementioned central air conditioning vents are fixed using threaded rods, rings, and brackets. The fixing method is the same as that of expansion bolts, where the brackets are opened or closed by turning the threaded rods to fix the vent frame grille. However, this method requires constantly turning the threaded rods, resulting in low efficiency in disassembly and installation.

[0005] Therefore, it is necessary to provide a new frame component and a new central air conditioning system to solve the above-mentioned technical problems. Utility Model Content

[0007] The frame component of the central air conditioning system provided by this utility model includes an air outlet duct and an air outlet frame grid. The air outlet frame grid is connected to the air outlet of the air outlet duct through multiple quick-release components.

[0008] The quick-release assembly includes a fixed base, a connecting base, and a movable rod. The fixed base is fixedly installed at the air outlet of the air outlet duct. The fixed base has a cross-shaped through groove and a limiting groove. The connecting base is fixedly installed on one side of the air outlet frame grid. A fixing plate is fixedly connected to the inner side wall of the connecting base. One end of the movable rod passes through the middle of the connecting base and the fixing plate. The bottom of the movable rod has a locking block that matches the size of the limiting groove. The outer surface of the movable rod also has an elastic reset member. One end of the elastic reset member is fixedly connected to one side of the fixing plate.

[0009] Furthermore, the bottom of the connecting seat is also provided with a rotating baffle, one end of which is fixed with a movable column. One end of the movable column is rotatably connected to the bottom of the connecting seat. The outer surface of the movable column is also provided with a torsion spring, and the two ends of the torsion spring are respectively fixedly connected to the inner side of the rotating baffle and the bottom of the connecting seat.

[0010] Furthermore, an air conditioning access port is provided on one side of the air outlet duct, and an installation plate is fixedly installed at the air conditioning access port by two connecting components.

[0011] Furthermore, the elastic reset component includes a connecting plate and a compression spring. The connecting plate is fixedly installed on the outer surface of the movable rod, and the compression spring is sleeved on the outer surface of the movable rod. The two ends of the compression spring are respectively fixedly connected to the connecting plate and the fixed plate.

[0012] Furthermore, the connecting assembly includes a mounting base, a connecting rod, and a support plate. The mounting base is fixedly installed at the air conditioner access port, the support plate is fixedly installed on one side of the mounting plate, and an adjustment groove is provided on the support plate.

The fixed base 3 has cross-shaped through slots 6 and limiting slots 7. The connecting base 4 is fixedly installed on one side of the air outlet frame grid 2. A fixing plate 8 is fixedly connected to the inner side wall of the connecting base 4. One end of the movable rod 5 passes through the middle of the connecting base 4 and the fixing plate 8. The bottom of the movable rod 5 has a locking block 9 that matches the size of the limiting slot 7. The outer surface of the movable rod 5 is also provided with a connecting plate 14 and a compression spring 15. The connecting plate 14 is fixed... The spring 15 is fixedly installed on the outer surface of the movable rod 5, and the two ends of the spring 15 are fixedly connected to the connecting plate 14 and the fixing plate 8 respectively. The connecting seat 4 of the air outlet frame grid 2 is aligned with the fixing seat 3 at the air outlet of the air outlet duct 1. The movable rod 5 passes through the connecting seat 4 and the fixing plate 8. The locking block 9 at the bottom of the movable rod 5 is aligned with the through groove 6 of the fixing seat 3 and inserted. At this time, the spring 15 is stretched. The movable rod 5 is rotated so that the locking block 9 is aligned with the position of the limiting groove 7, and the spring 15's rebound force drives the locking block 9 to be locked into the limiting groove 7 for fixation.

[0028] Example 2

[0029] In a specific implementation process, refer to Figure 3 As shown, the bottom of the connecting seat 4 is also provided with a rotating baffle 10.

The outer surface of the movable column 11 is also provided with a torsion spring 12. The two ends of the torsion spring 12 are respectively fixedly connected to the inner side of the rotating baffle 10 and the bottom of the connecting seat 4. The rotating baffle 10 provides auxiliary protection for the movable rod 5 through the elastic support of the torsion spring 12. When disassembly is required, the rotating baffle 10 is manually pushed outward to expose the movable rod 5 for easy pressing operation. After disassembly, the baffle is released and the torsion spring 12 automatically resets it to restore the protection state.

[0030] Example 3

[0031] In a specific implementation process, refer to Figure 1 as well as Figure 5 As shown, an air conditioning access port is also provided on one side of the air outlet duct 1 to facilitate the maintenance of the air conditioning components. An installation plate 13 is fixedly installed at the air conditioning access port through two connecting components.

[0032] It should be noted that the connecting assembly includes a mounting base 16, a connecting rod 17, and a support plate 18.
